A loop fastening material having a backing of orientable material and a multiplicity of fibrous elements extending from the backing. The fibrous elements are formed by filaments positioned on the backing and secured to the backing when the orientable material of the backing is in its dimensionally unstable state. The filaments are preferably positioned on the backing parallel to each other and essentially parallel to the path of response of the orientable material. The filaments are intermittently secured to the backing at spaced, fixed regions along the filaments so that each pair of fixed regions defines therebetween an unsecured catching region. Thus, the fibrous elements are formed by the shirring of the filaments at the catching regions when the orientable material is caused to be transformed to its dimensionally stable state such that it is caused to contract or gather along its path of response. The loop fastening material is formed by a method comprising the steps of: providing a backing of orientable material in its dimensionally unstable state; positioning a plurality of filaments on the backing; securing the filaments to the backing at spaced, fixed regions along each of the filaments, the fixed regions defining between each pair an unsecured catching region; and causing the orientable material to be transformed along its path of response to its dimensionally stable state thereby shirring the filaments at the catching regions to form fibrous elements projecting from the backing between the fixed regions.
